Optical Ground Wire OPGW 12 Core 24 Core 48 Core 96 Core Optical
Fiber Composite Ground Wire
Description
The Central Tube Optical Ground Wire (OPGW) is a type of cable that is used in overhead power lines. Such cable combines
the functions of grounding and communications. An OPGW cable contains a tubular structure with one or more optical fibers in
it, surrounded by layers of steel and aluminum wire. The OPGW cable is run between the tops of high-voltage electricity pylons.
The conductive part of the cable serves to bond adjacent towers to earth ground, and shields the high-voltage conductors from
lightning strikes.
Characteristic
1. Replace existing aerial ground wires, upgrading communication
lines of power systems.
2. Synchronous plan and design with ground wire when new aerial
power lines are to be constructed
3. Provide stainless tube fiber unit with optimal protection
4. Conduct large fault short-circuit current and providing
lightning protection
5. Suitable for application in hih fiber count and super high
voltage power lines
6. Match with favorable tension-sag of the diffluent grond wire.

Typical Design for Single Layer
Superior Lightning Resistance
• Fewer Aluminium Alloy (AA) wires are needed to meet electrical
specs
• More/Heavier duty ACS wires can be used
• AA wires can be completely replaced with ACS in some applications
Extruded Aluminium Core tube
• Good combination of crush and kink resistance
• Core tube can safely and easily be routed to closures without
armour
• Easy access to optical core Superior
Electrical Performance
• Aluminium core tube substantially increases conductor
cross-section
• Improved short-circuit capacity
High performance. Even in High fibre Counts
• All fibres are housed in the core tube
• Core tubes are available in a wide range of Inside Diameters
• Armour wires are not replaced with fibre tubes in high count
designs
